Abstract: A method for storing, organizing and providing remote electronic access to documents. A coversheet including a standard set of identification data characterizing each document is developed and stored. A digital version of each document is created and stored by scanning each contract. Each digital version includes a scanned image and a searchable text file, wherein the text is overlaid with the image. An index of bookmarks identifying sections of the digital version of each document is generated. Selected fields of information are captured from the digital version of the document. The documents are organized and cross-referenced in a database that includes the captured information and additional information related to each document. Designated parties are alerted of critical dates associated with each document. Remote electronic access to the documents is provided over the internet.

Abstract: A method of remanufacturing a shell of a heat exchanger is provided. The shell has an inner surface that defines an inner diameter thereof and the inner surface has a worn portion adjacent to an end of the shell. The method includes machining the inner surface to remove the worn portion and machining to form a tapered surface adjacent to the end of the shell. A diameter of the tapered surface increases progressively from the inner diameter of the shell to a maximum diameter at the end of the shell.

Abstract: Improved compositions comprising a mixture of particulate materials with water-based liquids containing water-soluble polymers and surfactants are provided. Examples of particulate powders include mixtures of calcium silicate, calcium aluminate, calcium sulfate, and hydroxyapatite. Examples of water-soluble polymers include polyvinyl alcohols, polyvinyl pyrrolidone, partially hydrolyzed polyvinyl acetates, polyacrylic acid, and polymethacrylic acid. Surfactants such as sodium dodecyl sulfate are added to the composition to interact with the polymeric materials. The compositions are particularly suitable for sealing and obturating dental root canals and root apices. The composition provides a stable barrier to bacterial and fluid leakage in the root canal system of a tooth. In addition, the compositions help promote the growth of new bone and tissue surrounding the root-tip area or dentin tissue that covers an injured or amputated pulp.

Abstract: A torque coefficient measuring device can be used to measure an axial load produced by a torque applied to a threaded component which is mounted to the fixture. The measuring device can include a base defining a chamber therein. A load sensor is disposed within the chamber of the base. A movable load pin is housed within the base and arranged such that an axial load placed upon the load pin is transmitted to the load sensor. An attachment member is adapted to be connected with the threaded component. The attachment member is operably arranged with the load pin such that a torque applied to a threaded component mounted to the attachment member places an axial load upon the load pin.

Abstract: A coaster or trivet includes a liquid impervious base and a liquid absorbent gel disposed on the base. The gel may comprise a hydrogel including a plurality of gel layers. Each gel layer is a different adhesive property with a first gel layer having a relatively high peel strength for contacting the base and a second gel layer having a relatively low peel strength for removably contacting a container.
